The Function of Silk
Silk is natural fiber. It has unique feature and powerful vitality which other fiber and artifact cannot fill in. The costuming made of silk has several health care effects of human beings:
First is the comfortable sensation. Real silk is made of azelon. It has a good biology compatibility with human bodies. Furthermore, the silk surface is smooth so it has the smallest friction coefficient of all kinds of fibers.
Second, it has a good hygroscopicity and permeability. Silk is a kind of azelon, it contains 18 kinds of amino acid. Because of its soft gloss, excellent permeability and extinction, silk was hailed as “ Queen of Fiber”.
Third one is the acoustic absorptivity, dust absorption, and thermostability.
Forth is the feature of ultraviolet radiation-resistance. Fibroin can absorb ultraviolet radiation, thus it has the function of ultraviolet radiation-resistance.
The Distinguish of Real Silk
The most commonly used methods are handle and eyeballing, inflammation, and chemical coloring.
Handle and eyeballing method:
Observe the length and trimness of fiber: silk is thin and long; cotton fiber is shorter; fleece is longer than cotton fiber and it is curled; the long chemical fiber is quite long, and the short chemical fiber is short but trim.
Observe the handle and intensity of fiber: the handle of real silk is moderate; viscose, nylon yarn, and terylene are similar with silk; cotton and flax are stiff, but fleece is very soft.
Observe the fiber by snapping it: silk, flax, cotton, and composed silk are strong in tenacity; fleece, viscose and cellulose acetate fiber are tender.
Observe by its appearance: silk fiber has a special gloss, it is bright but not glare; chemical fiber does not have this feature.
Inflammation method:
Burn the fiber and observe the change of fiber to determine its category.

The Maintenance of Real silk
The dyestuff of real silk is mainly CI acid dyestuff, neutral dyestuff and parts of direct dyestuff. The firmness of silk coloration is relatively poor, so it is not suitable to wash under high temperature. In addition, silk is not alkali resistant. Wash it with neutral soap or other silk product detergent. You can also use dry cleaning.
It is not suitable to wash silk with other white or light color garments. It is also not suitable to scrub hardly. It is inadvisable to wash silk in the washing machine.
The dyed silk garments should be placed in cool and dry places where the direct rays of the sun will not beat.
It is not suggested to wring the silk garments after wash. If use electric iron, be careful that the temperature should not be too high.
